The screw members S respectivelypassing through the screw holes 510 respectively pass through the screwholes 312 and 313 of the board support 300 and the screw holes 132 and133 of the bottom cover 100 to screw-couple the bottom cover 100 to theback cover 500.

The latch hole 520 is defined in a bottom surface 502 of the back cover500 and is provided in plurality. The plurality of latch holes 520 arespaced a predetermined distance from each other, and the latchprotrusions 210 disposed on the lower edge of the cabinet 200 areinserted into and mounted on the plurality of latch holes 520. Thus, thecabinet 200 may be hook-coupled to the back cover 500.

The hook protrusion 530 is hook-coupled to the board support 300 and isprovided in plurality. The plurality of hook protrusions 530 are spaceda predetermined distance from each other along an upper edge of the backcover 500. The plurality of hook protrusions 530 is hook-coupled to thehook mounts 330 of the board support 300, respectively. Thus, the backcover 500 may be hook-coupled to the board support 300.

The back cover rib 540 is spaced a predetermined distance from the edgeof the back cover 500 to protrude from a front surface 504 of the backcover 500. The plurality of back cover ribs 540 are spaced apredetermined distance from each other along the edge of the back cover500 and then are fitted into the board support 300.

Among the plurality of back cover ribs 540, the back cover ribs 540disposed on both sides of the front surface 504 of the back cover 500are hook-coupled to the hook mounts 330 disposed on both side surfaces304 of the board support 300.

As described above, in the current embodiment, since the back cover 500is hook-coupled to the bottom cover 100, a smaller number of screwmembers S, i.e., the two screw members S, may be used.

Thus, the display apparatus (see reference numeral 1 of FIG. 1)according to the current embodiment may be improved in assembly processefficiency and reduced in manufacturing cost.

Also, the display apparatus 1 according to the current embodiment may besignificantly reduced in the number of components required forassembling by the modification in component assembly structure.Therefore, the display apparatus 1 may be reduced in width of a bezel.

Thus, the display apparatus 1 according to the current embodiment mayrealize the slimmer display apparatus 1 according to the trend of theslimness in recent years.

FIG. 32 is a view illustrating an assembly process of the bottom coverof FIG. 31 and a stand of FIG. 2.

Referring to FIG. 32, the display apparatus 1 may be completelyassembled by coupling the stand 600 to the bottom cover on which theback cover 500 is mounted. The coupling of the stand 600 may beperformed by an individual user. That is, in the current embodiment, thedisplay apparatus 1 except for the stand 600 can be sold, and then theuser can finally couple the stand 600 to the display apparatus 1.

Therefore, the display apparatus 1 according to the current embodimentmay be reduced in volume occupied for packaging the product when theproduct is sold.

According the various embodiments as described above, the displayapparatus having the simple structure that is capable of improving theassembly process efficiency and reducing the manufacturing costs may beprovided.

Although embodiments have been described with reference to a number ofillustrative embodiments thereof, it should be understood that numerousother modifications and embodiments can be devised by those skilled inthe art that will fall within the spirit and scope of the principles ofthis invention. More particularly, various variations and modificationsare possible in the component parts and/or arrangements of the subjectcombination arrangement within the scope of the invention, the drawingsand the appended claims. In addition to variations and modifications inthe component parts and/or arrangements, alternative uses will also beapparent to those skilled in the art.
